The hashtag was coined earlier this month by Twitter user princess_labia, who likened a photo of her thighs to the practice of reading the lines on one's palm.
Since then, women have been posting photos on various social media networks, and sharing the stories of their lumps, bumps, and other so-called flaws...
...including stretch marks...
...scars...
...cellulite...
...and more.
Even those not posting their own photos are getting in on the body-positive party.
"Because we never see any images in the media that are not photoshopped or altered in some way, [we] feel the way the way we look is not normal," princess_labia told MTV News.
"[The response to the hashtag is] exciting because you get responses like, 'I didn't realize how many girls had this' or 'it makes me feel more comfortable having these' or 'the more I look at them the more beautiful I realize they are.'"
